Synthesis of Sulfur-Containing Analogues of Hedychenone, a Labdane Diterpenoid from .

The labdane diterpene hedychenone, isolated from , is an example of a furan-containing natural product. Herein, a new and efficient method for the synthesis of 19 new thio analogues of hedychenone is reported. The present methodology exhibits a broad substrate scope with good to excellent yields without metal or base under mild reaction conditions.

Isolation, characterisation, antifungal activity and validated UPLC/MS/MS method for quantification of novel compound from Reichb.

Investigation into the chemical diversity of resulted in isolation of one novel compound named tournefortin A and two known artemetin and tournefortin B bioactive compounds. Tournefortin B is first time obtained from natural source. The structure of all the isolated compounds were elucidated by detailed 1D and 2D NMR including HSQC, HMBC, H-HOSY and NOESY spectroscopic techniques.

Volatile composition, antibacterial and antioxidant activities of Reichb. from Kashmir, India.

The importance of the present study is to find out the phytochemical profile of essential oil (EO) of Reichb. and its biological evaluation. Nineteen volatile constituents were identified from EO representing 93.

Chemical composition, antioxidant and cytotoxic activity of essential oil growing wild in Kashmir valley.

The present study was carried to observe the phytochemical profile of aromatic constituents of essential oil using GC-FID, GC-MS and C NMR and to evalute anticancer and antioxidant activities. Twenty chemical constituents were detected from EO accounting 92.05% of total oil composition.
